Associating Behavior of Mixed Liquids: Dielectric Properties of the Ethane-1,2-Diol+1,4-Dioxan Solvent System From -10 to +80°C

Abstract

The associating behaviour of ethane-1,2-diol (component 1)+1,4-dioxan (component 2) in their binary mixtures has been investigated through their dielectric properties. The experimental measurements of the relative permittivity (є) in the temperature range -10 ≤ X₁ ≤ 80 for nine binary mixtures covering the whole miscibility field 0 ≤ X₁ ≤ 1 have been utilized to test empirical equations representing the functions є = є(T), є = є (X₁) and є = є(T,X₁). Furthermore, the excess mixing function, єE, has been evaluated to obtain qualitative and quantitative information about the possibility of 'solvent- cosolvent ' complex formation.
